RAILWAY-CAR SIDE BEARING.

Specification of Letters Patent.

Applicationlletl July '15, 191/6. Serial No. 1095422.

T 0 all whom it may conferir: 4

Be it known that .T ouN F. OCoxivon, a citizen of the United States. residingr at, Chicagtndn the county of (look and State of illinois. have invented a certain new and useful improvement in Railway-C11r Side Bearings'. of which the( following is a full, clear, concise, and e'xat't description. reference, heingfhad to the accompanying drawings, formingY a part 'ofthis specification.

This invention relates to improvements in railway ear side hearing.

One object of the invention is to provide a simple. relatively cheaproller side bearing.r for railway cars and so arranged that the roller will he auton'iatieally returned to eent.ral or normal (position after each aetuation.

'Another and more specific ohiect of the invention is toprovide a roller side l'iearing havingr a. rockert ilt ed by the roller during the movements of the latter. the, ro-ker returnin;r the `roller to normal position under the' influence. of gravity. when pressure onthe, roller is removed.

Tn the drawingr forming a part of this' specification` `Figure 1 is an end elevation oi a body and truck holster of a rar and showing my iinproveinents in connection Fig. 2 is an eniarged top plan view of the improved side, hearing proper. Fig. 3 is a longitudinal, vertical section taken on the line 3-3 of Fig. 2. And Fig. 4. is a perspective view of the rocker.

in said drawing. l() denotes the body bol- .ster and l1 the trut-k bolster which are pivotally conneeted at their centers in the usual manner. As shown, the hotly holster is p rovided with a strikingl plate 12 and the truck bolsterfjhas applied thereto the improved side bearingr designated generally by the reference A.

The improved side. bearing A preferably comprises a base member or casting B which is riveted or otherwise suitably secured to the.` truck bolster. and an anti-friction roller (i. The hase member ll is of substantially box-like form` open atzfthetop. and has outwardly extended bottom [langes iii-through which pasa. the securingr means and on its interior theI base member is provided with a suitable inserted tread or wear plate on which the roller (l operates;

The retaining member or hase. casting: B is provided with side walls isi-J5 and end walls 1(3-16, the latter limiting the movements ot the roller. as clearly appears from the dotted lines shownin Fig. 3. It will be noted that the end walls lare Ainwardly inclined as indicated. at 17-17 and from between the loutermines of said portions 17 Patented Jan.-7, 19119.

andthe raised central portion 18 of the -laatse casting. on whirh is seeured the tread plate 14, are formed sockets or bearings l19-19 for the. transverselyextending rounded edges Z0-S20A at the rocker designated generally by,

Said' roeker'D is vot substantially rectangular form, as clearly' in'- dicated in Fig. 4 and tits around the roller the reference D.

C. The distance between the end/walls 2l-Q1 of the rocker D is' slightlyless 'than the diameter of the roller C. Hence, 'as the roller C is movedrto one side orther other of its normal position, it will engage one 'of the end walls 21 of the ro'ker on the curved.

portion indieated'at, 22 and continued more@ ment of the roller will tilt, the rocker l) about one of itsredsres 20. as indi"atd'by heling in an unbalanced condition, will obvithe dotted lines'in Fig'. When pressure` on the roller C is removed. the ro'ker D v f`V ously return to normal under the iniiuenceof gravity vand in so doing. will torre the roller` hack to normal position. lt is obvious from the. construction shown that the rocker D operates the same whether tilted to one side; or the, other. The outer surfaces ZB-JJB of the end walls 2i of the rocker Dy f are preferably of sir'h contour ns to tit the inner surfaces of the portions l'-IT when the roller has been moved to its fullest extent so that the upper portion of the end walla` 16 of the hasey easting andthe end -.wallsv QIY--Q of the rocker eoperate in limitiniz the movement of the roller. thus distributing the stresses over a greater arca.

From theI preceding description, it will be seen that l have prevideda roller side bearing which may he. relatively cheaply manufactured: wherein is employed a roller of comparativelylarge diameter presenting a wide hearingr surface: and wherein the, roller is always returned automaticallyy to normal position after each actuation,

l claim:

l. ln a roller side bearing. the combinan tion with n retaining member, and a roller bodilv movable therein and directly nearing on a portion thereof` of means for returning' Isaid roller to normal position after actuation thereof, said means comprising, a rocker loe normal position.

2. In a roller side bearing, the combina-V tion with a retaining member, and a roller bodily movable therein, of means for returning said roller to normal position after actu.- ation thereof, said means comprising, a mein berl mounted in said retaining member and adapted to be rocked aboutgpeither end there'i of as a pivot, the roller engaging one end of said member when moved in-one direction and the opposite end when moved in the other directiony 3. In' a roller side bearing, the combination witha retaininggnember, anda roller bodily movable therein, of means for return- 'ing said rollerto normal position after actuation thereof, said means comprising,` a rocker within whlch said roller 1s mounted, said rocker, being adapted to tilt about two 'otlits edges depending' upon the direction of movement of t e roller,

4. In a roller side bearing', the combination with a base casting of substantially rectangular form, of a rectangular rocker re movably mounted Within said casting, the

rocker being adapted to be oscillated about either end thereof, and a roller mounted on a portion of the base casting and confined within the said rocker, the roller actuating the rocker to oscillate it about either ot said ends. i

5. In a roller side bearing, the combination with a base casting having a central tread portion, of a roller mounted on said tread portion', and a hollow, substantially rectangular rocker surrounding'the lower portion of provided with a pair of bearings and the rocker having two of its edges rounded to cooperate with said bearings.

6. In a roller side bearing, the combination with a hollow base casting having a centrally raised tread portion, of a rocker of substantially rectangular form having its end Walls rounded at their lower edges, the base casting being provided with coperatsaid roller, said base casting being in@ bearings for sald edges to thereby pcr- .mit the roller to tilt about either end, and a rollermounted on said tread portion and Withinsaid rocker, the diameter of the roller being in excess of the distance between the upper' portions of the end walls ,of the rocker.

In witness that I claim the foregoing I have hereunto subscribed my name this 13th day of July 1916.
